Windows 7: Secure Boot Violation when trying to set CD drive to install Win 7

Secure Boot Violation when trying to set CD drive to install Win 7

Hi All,

My son dropped a book on his Samsung Np355V5C at uni the other week and cracked his screen. So now he is home for easter I've changed the screen but he has killed the hard disk at the same time though I am able to recover his docs using easeus recovery program.

I have gone and got him a new 1TB western Digital Hard drive today and fitted it but had the following problems when i tried to install Windows 7 Pro

I read through your clean install guide and reset the BIOS to defaults but when i then change the boot proirty to cd i get a red label saying

Secure Boot Violation

Invalid Signature detected. Check secure Boot Policy in Setup


After restoring to defaults the boot order looks like this

Boot option Priorty

Boot option 1 [Windows Boot Manager (P0: WDC WD10JPVX-22JC3T0)
Boot Option 2 [Windows Boot Manager (P0: WDC WD10JPVX-22JC3T0)
Boot Option 3 UEFI: TSSTcorp CDDVDW SN-208DN

I have a windows 7 pro disk which has worked previously so could use some help please.

I dont' understand what is going wrong

Disable secure boot if possible.

Enable Legacy Boot or Legacy and UEFI Boot (yes sometimes they show as combined) in the Bios, if possible.

Boot device priority has nothing to do with boot order.

Just use the 1 time boot function key ( F8 etc. whatever it is for your model and choose the dvd rom )

Why didn`t you buy him a solid state drive For shame, Bad Daddy

Thanks for that, it worked to a point. I disabled secure boot and select UEFI mode. The cd started to load, it said it was loading windows setup files, then the windows logo briefly came on the screen but then turned to a black screen with a movable mouse cursor and nothing happened. I tried pressing "shift & F10" as described in Black screen with only mouse cursor on it - Windows 7 instalation but nothing happened. Please can someone give me further help to get this laptop up and running.

I've got to to be honest, I don't understand why i would want to fit a small SSD to his laptop when it only has one bay for a hard disk, and I couldn't afford a 1TB one anyway

Hi and welcome to SevenForums
Yep a 1tb ssd would leave a dent in the pocket book plus the other fixes :)
No telling what other damage has been done to other hardware either.

You might try disabling fast startup
If you see anything about CSM in advanced it would need to be enabled.

You could use an win-7 iso and use rufus on option 2 here it has uefi compatibility

Because a solid state drive is better.

Why would anyone need a 1 TB SSD ??????

So guys, I made the rufus usb installation drive but couldn't get it to work. I've tried all different options but it never appears in the boot menu. I have a very simalar laptop a samsung np355v5c-A06UK whereas my sons is just a np355v5c.

Maybe I'm being a bit thick here but could i install my hard drive into his machine to see if it would run or would it make changes to my drive and knacker it?

I found an old linux boot cd with testdisk and gparted on it. Although they both could see the new hard disk neither could perform any tests on it so my own conclusion is there is damage to the motherboard which is stopping all the usb ports and hard disk working properly.

So if anyone has any ideas how to find out what else he could have fried when he dropped a book on his screen I'd be very grateful

I believe you could start the install on another machine and when it restarts for the first time just power off with holding down the power button on the case.
Then install the hdd in the other machine and power up
The installer should continue
AddRam came up with that little trick might be worth a try what is there to loose ?

There are a few chips that may have become dislodged
The cpu is most likely welded to the mobo not to mention it has a clamp to hold the heat sink on so I doubt anything moved it.

Exactly. I refuse to repair anyone's laptop for them anymore if they're not using an SSD in it for their o/s . There's no excuse for this anymore. SSD's are cheap and external storage drives are even cheaper. 240 Gb is more than enough to get by with a laptop and at 50 cents a Gb with SSDs there are no more excuses.

(Then again, a 1TB SSD would be a sweet thang.) Just sayin' :)
